Answer:
m ∠A =90°, m ∠B =60°, and m ∠C =30°
Step-by-step explanation:
If a > b> c you know the the side opposite ∠ A is the longest side and the side opposite ∠C is the shortest side.
side BC is the longest side, side AB is the shortest side, and side AC measure is the second longest side.
Draw the Δ ABC and label the longest side, shortest side, and the middle side. Now the longest side is opposite the biggest angle, the shortest side is opposite the smallest angle.
m ∠A =90°, m ∠B =60°, and m ∠C =30°

Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ ≥ 50000
For the alternative hypothesis,
µ < 50000
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = lifetime of the tyres
µ = mean lifetime
σ = standard deviation
n = number of samples
From the information given,
µ = 50000 miles
x = 45800 miles
σ = 8000
n = 29
z = (50000 - 45800)/(8000/√29) = - 2.83
Looking at the normal distribution table, the probability corresponding to the z score is 0.9977
Since alpha, 0.05 < than the p value, 0.9977, then we would accept the null hypothesis. Therefore, At a 5% level of significance, the data is not highly consistent with the claim.
Answer:
Federalism is a mixed or compound mode of government that combines a general government (the central or "federal" government) with regional governments (provincial, state, cantonal, territorial or other sub-unit governments) in a single political system.
